The IRQ probing is needlessly complex. All off the 83xx device trees in arch/powerpc/boot/dts/ specify 5 interrupts per DMA controller: one for the controller, and one for each channel. These interrupts are all attached to the same IRQ line. This causes an interesting situation if two channels interrupt at the same time. The per-controller handler will handle the first channel, and the per-channel handler will handle the remaining channels. Instead of this mess, we fix the bug in the per-controller handler, and make it handle all channels that generated an interrupt. When a per-controller handler is specified in the device tree, we prefer to use the shared handler instead of the per-channel handler. The 85xx/86xx controllers do not have a per-controller interrupt, and instead use a per-channel interrupt. This behavior has not been changed. Signed-off-by: Ira W.
